I applied in-person. The process took 1 day. I interviewed at Amazon (Seattle, WA) in Jan 2017
Interview
I got an Online Assessment for the first round, it includes 20 mins for debugging and 35 mins for reasoning question. Debugging session contains 7 simple questions. With the 2nd part, you have to practice in GMAT and GRE math session, and you have to pass 24/24 questions. With me, I think this is an unfair way to choose the candidate for the next round. You have to pass this round before moving on the coding round, so I recommend practicing GRE and GMAT a lot.
Recruiter screen, followed by an online coding assessment and then a technical phone interview. The final round was a virtual onsite loop with multiple interviews covering data structures, system design, debugging, and Amazon Leadership Principles. The technical questions were practical but time-constrained, and the behavioural questions required specific examples using the STAR format.

Question 1
Design a scalable URL shortening service and explain how you would handle high read traffic, collisions, database schema, expiration, and basic monitoring.
That moment when the interviewer asked about finding indices in an array for a target sum was wild — I had just tackled something identical while prepping on PracHub. The interview included a technical round with another question about designing an in-memory LRU cache and a behavioral question about meeting tight deadlines. After a smooth discussion, I was told I'd received an offer, which I happily accepted. Overall, the process felt pretty straightforward and not overly challenging.

Interviewed for silicon team. Have only been asked about the domain specific knowledge in 1st round and system design in 2nd round and C coding in 3rd round.
The interviews were 50 mins each.
